如何开发供应商库?

I recently jumped back into an old Go project and migrated it to the vendor approach, using dep

It completed sucessfully and I now have a bunch of libs in the local projects vendor/ directory. Great!

However, I now want to work on one of those vendored libs, and see the changes in my main app live. The lib exists in its own project of course, doesn't live its life in this other apps vendor folder - and other local projects should be able to see the live changes too if necessary.

I'm thinking something like npm link, to compare across ecosystems.

How is this typically managed in Go?
